What's New in Sailthru

August 25, 2025

 

Media Library - Rollout Starting

 

Background

Image assets have lived separately within each visual editor: Visual Email Templates, Visual Overlays, and Visual Hosted Pages. This leads to duplicate uploads and added effort when managing media.

Solution

Sailthru is introducing a new Media Library directly from the dropdown menu under the ‘Messaging’ tab. The Media Library will be shared across all Visual Editors (Visual Email Templates, Visual Overlays, and Visual Hosted Pages). This update simplifies asset management by consolidating your images into a single location so there will be no need to upload the same image multiple times for different editors. For existing customers, your image assets will be automatically available inside the new Media Library for use.

What this looks like in Sailthru

Under the Messaging tab in Sailthru, you’ll find the new centralized Media Library, giving you a single place to manage all your image assets. Any images you add here will be accessible across Visual Email Templates, Visual Overlays, and Visual Hosted Pages, creating a unified experience that reduces the need for duplicate uploads.

If you access the Media Library from within a Visual Editor, the experience will feel familiar. There are no changes to how you select, upload, or organize images within the editor. What’s new is the unified backend, which ensures your media is synced across all visual editors.

We’re also introducing a new Zephyr function—media—which makes it easier to insert images into HTML templates where Zephyr is supported. For example: {media("/April/promo.jpg")}

SMS in Event Stream

Background:

Until now, SMS event data was not available via Event Stream, limiting visibility into SMS engagement for marketers.

Solution:

Sailthru is adding a new SMS data set to Event Stream. SMS campaigns and triggered events are now available in an hourly CSV export, giving customers timely access to key SMS activities like sends, bounces, and clicks. No additional configuration is required. The export will appear automatically in the customer’s configured S3 bucket for Sailthru Connect customers using SMS.

What this looks like in Sailthru:

These exports will appear in your configured S3 bucket as part of your Event Stream exports.

The following tables will be included:

  • sms_campaign_send
  • sms_campaign_bounce
  • sms_campaign_click
  • sms_triggered_send
  • sms_triggered_bounce
  • sms_triggered_click

Each table will be exported hourly and will reflect new SMS event activity beginning July 29, 2025. For a full list of the included field names, see the SMS in Event Stream documentation.
